Watch Nick Diaz Work the Speed Bag For 23 Consecutive Minutes in Preparation For GSP at UFC 158

Nick Diaz takes on Georges St. Pierre for the UFC welterweight title Saturday in Montreal. As you can see from this video that shows Diaz working a speed bag for 23 consecutive minutes, he is in pretty good shape. That should come as no surprise since Diaz often competes in triathlons and is known for his great conditioning. In fact, the only reason this video stands out is because most people will get tired just watching it. And for the record, while this video has over 138k views, I don’t think everyone watched all 23 minutes.
